[cctest] Check compilation result in v8_compile

Browse Source 
This CL introduces a CHECK in v8_compile that compilation succeedes.
Previously, a failed compilation would lead to undefined behavior or
a crash in CompileRun, because it would call Script::Run on a nullptr.
This CL introduced v8_try_compile that returns a MaybeLocal and supports
test-cases that want to ensure that a compilation fails.
